Improved construction of glass bottles



FRANKLIN N. BULLARD, OF WORCESTER, MASSACHUSETTS.

IMPROVED CONSTRUCTION OF GLASS'BOTTLESK.

Specification forming part of Letters Patent No. 59,333, dated October 30, 1866.

To all lwhom it may concern:

Be it known that I, FRANKLIN N. BULLARD, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in the Construction ot' Glass and other Bottles, for the purpose of economizing space, facility, and security in packing the same for transportation; andl that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l represents two ofthe bottles placed together, and which, when so placed, form nearly a perfect square, the corners being slightly rounded. Fig. 2 represents a transverse section through two of the bottles, showing how they will pack into a square, or nearly so, form. Fig. 3 represents how four of the same shaped bottles would pack in a square form, and, by the red dotted lines, how eight similarshaped bottles would packinto a square form, or nearly so, and any multiples of these numbers would accomplish the same result.

I am aware that triangular-shaped bottles of equilateral sides and uniform angles have been made. These bottles will not pack into squares, and I therefore lay no claim to such. Nor do I claim square, round, or manysided bottles, in any of their forms or shapes, as they will not pack into squares for transportation, as those I propose will do.

My invention consists in the construction of glass or other bottles of a triangular form,

and whose greatest angle shall be a right angle, or ninety degrees, and whose lesser angles shall be of halt' a right angle, or forty-tive degrecs, so that two, four, eight, sixteen, or multiples of these numbers, may be put together in a square form for economy and safety in packing.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

A A represent two bottles of the form I propose. The greater angle, a, of these bot tles, or the angle that its sides produced would form at a, is a right angle, or an angle of ninety degrees. The other two angles, c c, or where the angles, if the sides were produced, would be acute, and half of a right angle, or forty-tive degrees 5 and these same angles pervade the whole system, or multiples of twos, fours, 85o., throughout, and maybe of any size that is uniform, so long as the greater angle is a right angle and the lesser angles halt' a right angle, as they will thuspack into squares.

In Fig. 3, I' have shown, in dark sectional 1incs,.how four of such triangular-shaped loottles will form a square, the angles at a and at c c bearing the same relation to each other as those in Fig. Z-viz., ninety and forty-tive degrees; and by the red dotted lines in Fig. 3 I have shown how eight bottles of this precise form and relation of angles to'each other will also pack into a square.

I have called these iigurcssquares. They are nearly so, the corners of the bottles being slightly rounded o', which is almost a matter of necessity, as molded glass cannot be brought to a sharp corner without making the glass so thin as to be easily broken 5 and hence they arc rounded off.

It'will be observed, as one ot the peculiari-- tics of my construction of bottles, that the square will always be divided diagonally at least in one direction, if not in both. Two

bottles will divide it but once diagonally, as

in Fig. 2. Four will divide the square diagonally in both directions, as seen in Fig. 3 in sectional lines. Eight will divide the square both diagonally and equilaterally, as seen in the full and dotted lines of Fig. 3.

My invention would be readily distin guishcd -from the packing of square or four-sided bottles, if even I had not disclaimed such, as I have done, for, with square bottles, two or eight will not form a square, while twoor eight of mine will form a square.

i The object of this particular form ot bottle is to econcmizc room, facilitate the packing of such bottles, and render them secure from breakage in transportation. For all other pur-l poses of use they are as convenient as any other shaped bottle; but while I have defined the precise angles of the corners of my bottles so as to make them pack into squares, I am aware thata slight variation may be, and possibly would be, made to evade my invention,

and I therefore do not limit myself so closely as precise angles, but would claim substantially such angles as would accomplish the object aimed at by lne.

What I claim as my invention, and desire to secure by Letters Patent, isa-- The constructing` or 'makin g of glass or other bottles of a triangular form, and of such relative greater and lesser an gies as that two7 tour, eight,

or multiples ot' these numbers, will pack up in a square form for economy, facility, and security in packing and transporting them7 substantially as described.
